Abstract
In last twenty years, the significant development of AIE materials has been witnessed. A number of small molecules, polymers and composites with AIE activity have been synthesized, with some of these exhibiting great potential in optoelectronics and biomedical applications. Compared to AIE small molecules, macromolecular systems-especially well-defined AIE polymers-have been studied relatively less. Controlled polymerization methods provide the efficient synthesis of well-defined AIE polymers with varied monomers, tunable chain lengths and narrow dispersity. In particular, the preparation of single-fluorophore polymers through AIE molecule-initiated polymerization enables the systematic investigation of the structure-property relationships of AIE polymeric systems. Here, the main polymerization techniques involved in these polymers are summarized and the key parameters that affect their photophysical properties are analyzed. The author endeavored to collect meaningful information from the descriptions of AIE polymer systems in the literature, to find connections by comparing different representative examples, and hopes eventually to provide a set of general guidelines for AIE polymer design, along with personal perspectives on the direction of future research.

Abstract
A variety of poly(N-isopropylacrylamide) (PIPAAm)-grafted surfaces have been reported for temperature-controlled cell adhesion/detachment. However, the surfaces reported to date need further improvement to achieve good outcomes for both cell adhesion and detachment, which are inherently contradictory behaviors. This study investigated the effects of terminal cationization and length of grafted PIPAAm chains on temperature-dependent cell behavior. PIPAAm brushes with three chain lengths were constructed on glass coverslips via surface-initiated reversible addition-fragmentation chain transfer (RAFT) polymerization. Terminal substitution of the grafted PIPAAm chains with either monocationic trimethylammonium or nonionic isopropyl moieties was performed through the reduction of terminal RAFT-related groups and subsequent thiol-ene reaction with the corresponding acrylamide derivatives. Although the thermoresponsive properties of the PIPAAm brush surfaces were scarcely affected by the terminal functional moiety, the zeta potentials of the cationized PIPAAm surfaces were higher than those of the nonionized ones, both below and above the phase transition temperature of PIPAAm (30°C). When bovine endothelial cells were cultured on each surface at 37°C, the number of adherent cells decreased with longer PIPAAm. Notably, cell adhesion on the cationized PIPAAm surfaces was higher than that on the nonionized surfaces. This terminal effect on cell adhesion gradually weakened with increasing PIPAAm length. In particular, long-chain PIPAAm brushes virtually showed cell repellency even at 37°C, regardless of the termini. Interestingly, moderately long-chain PIPAAm brushes promoted cell detachment at 20°C, with negligible terminal electrostatic interruption. Consequently, both cell adhesion and detachment were successfully improved by choosing an appropriate PIPAAm length with terminal cationization.

Abstract
Among biocompatible materials, block copolymers (BCPs) possess several advantages due to the control of their chemistry and the possibility of combining various blocks with defined properties. Consequently, BCPs drew considerable attention as biocompatible materials in the fields of drug delivery, medicine and bioimaging. Fluorescent labeling of BCPs quickly appeared to be a method of choice to image and track these materials in order to better understand the nature of their interactions with biological media. However, incorporating fluorescent markers (FM) into BCPs can appear tricky; we thus intend to help chemists in this endeavor by reviewing recent advances made in the last 10 years. With the choice of the FM being of prior importance, we first reviewed their photophysical properties and functionalities for optimal labeling and imaging. In the second part the different chemical approaches that have been used in the literature to fluorescently label BCPs have been reviewed. We also report and discuss relevant applications of fluorescent BCPs in bioimaging.

Abstract
Chain-end-labeled polymers are interesting for a range of applications. In polymer nanomedicine, chain-end-labeled polymers are useful to study and help understand cellular internalization and intracellular trafficking processes. The recent advent of fluorescent label-free techniques, such as nanoscale secondary ion mass spectrometry (NanoSIMS), provides access to high-resolution intracellular mapping that can complement information obtained using fluorescent-labeled materials and confocal microscopy and flow cytometry. Using poly(N-(2-hydroxypropyl)methacrylamide) (PHPMA) as a prototypical polymer nanomedicine, this paper presents a synthetic strategy to polymers that contain trace element labels, such as fluorine, which can be used for NanoSIMS analysis. The strategy presented in this paper is based on reversible addition fragmentation chain transfer (RAFT) polymerization of pentafluorophenyl methacrylate (PFMA) mediated by two novel chain-transfer agents (CTAs), which contain either one (α) or two (α,ω) fluorine labels. In the first part of this study, via a number of polymerization experiments, the polymerization properties of the fluorinated RAFT CTAs were established. 19F NMR spectroscopy revealed that these fluorinated RAFT agents possess unique spectral signatures, which allow to directly monitor RAFT agent conversion and measure end-group fidelity. Comparison with 4-cyanopentanoic acid dithiobenzoate, which is a standard CTA for the RAFT polymerization of PFMA, revealed that the introduction of one or two fluorine labels does not significantly affect the polymerization properties of the CTA. In the last part of this paper, a proof-of-concept study is presented that demonstrates the feasibility of the fluorine-labeled poly(pentafluorophenyl methacrylate) polymers as platforms for the postpolymerization modification to generate PHPMA-based polymer nanomedicines.

Abstract
INTRODUCTION A major barrier to the advancement of therapeutic nanomedicines has been the non-target toxicity caused by the accumulation of the drug delivery systems in organs associated with the reticuloendothelial system, particularly the liver and spleen. Herein, we report the development of peptide based metabolically active linkers (MALs) that are enzymatically cleaved by cysteine cathepsin B and S, two proteases highly expressed in the liver and spleen. The overall goal of this approach is to utilize the MALs to lower the non-target retention and toxicity of radiolabeled drug delivery systems, thus resulting in higher diagnostic and radiotherapeutic efficacy. METHODS In this study three MALs (MAL0, MAL1 and MAL2) were investigated. MAL1 and MAL2 are composed of known substrates of cathepsin B and S, respectively, while MAL0 is a non-cleavable control. Both MAL1 and MAL2 were shown to undergo enzymatic cleavage with the appropriate cathepsin protease. Subsequent to conjugation to the HPMA copolymer and radiolabeling with (177)Lu, the peptide-polymer conjugates were renamed (177)Lu-metabolically active copolymers ((177)Lu-MACs) with the corresponding designations: (177)Lu-MAC0, (177)Lu-MAC1 and (177)Lu-MAC2. RESULTS In vivo evaluation of the (177)Lu-MACs was performed in an HPAC human pancreatic cancer xenograft mouse model. (177)Lu-MAC1 and (177)Lu-MAC2 demonstrated 3.1 and 2.1 fold lower liver retention, respectively, compared to control ((177)Lu-MAC0) at 72h post-injection. With regard to spleen retention, (177)Lu-MAC1 and (177)Lu-MAC2 each exhibited a nearly fourfold lower retention, relative to control, at the 72h time point. However, the tumor accumulation of the (177)Lu-MAC0 was two to three times greater than (177)Lu-MAC1 and (177)Lu-MAC2 at the same time point. The MAL approach demonstrated the capability of substantially reducing the non-target retention of the (177)Lu-labeled HPMA copolymers. CONCLUSIONS While further studies are needed to optimize the pharmacokinetics of the (177)Lu-MACs design, the ability of the MAL to significantly decrease non-target retention establishes the potential this avenue of research may have for the improvement of diagnostic and radiotherapeutic drug delivery systems.

Abstract
Facile derivatization of rhodamine 6G in the 2' position by direct reaction with secondary amines is reported. If the secondary amine contains a hydroxy group, the hydroxyl-functional intermediate can be readily esterified to give either fluorescent initiators for atom transfer radical polymerization (ATRP) or a fluorescent methacrylic comonomer. In contrast to rhodamine dyes functionalized using primary amines, which are only fluorescent at low pH, these compounds are highly fluorescent at physiological pH. These new compounds were subsequently used to prepare a range of fluorescently labeled biocompatible polymers based on the biomimetic monomer, 2-(methacryloyloxy)ethyl phosphorylcholine (MPC), for biomedical studies.

Abstract
In this study we give evidence that domperidone encapsulated into amphiphilic p(HPMA)-co-p(laurylmethacrylate) (LMA) copolymer aggregates is able to cross the blood-brain barrier, since it affected motor behaviour in animals, which is a sensitive measure for CNS actions. Carefully designed copolymers based on the clinically approved p(HPMA) were selected and synthesized by a combination of controlled radical polymerization and post-polymerization modification. The hydrodynamic radii (R(h) ) of amphiphilic p(HPMA)-co-p(LMA) alone and loaded with domperidone were determined by fluorescence correlation spectroscopy.

Abstract
A new approach to controlling the charge on gold nanoparticle surfaces is described. The method exploits the simultaneous coattachment of both charged and neutral polymers onto gold surfaces. The charged and neutral polymers were synthesized by reversible addition-fragmentation chain transfer (RAFT) polymerization, and the RAFT end-group functionality was used as the anchor for attachment to gold. The approach described is general and can be applied to a wide range of monomers; those exemplified in the paper are poly(2-aminoethyl methacrylamide) (P(AEA)), poly(acrylic acid) (PAA), and poly(N,N-diemthylaminoethyl acrylate) (P(DMAEA)) together with neutral polymers based on poly(oligoethylene oxide) acrylate (P(OEG-A)). The hybrid polymer-stabilized GNPs thus formed were characterized in solution using dynamic light scattering and zeta potential measurements, transmission electron microscopy, UV-visible spectroscopy, X-ray photoelectron spectroscopy, and attenuated total reflection-Fourier-transform IR spectroscopy. The grafting densities of the polymers on GNPs were measured using thermal gravimetric analyses (TGA), as 0.4 chains/nm(2) (for PAA), 0.9 chains/nm(2) (for neutral polymers, such as P(NIPAAm), and 0.6 chain/nm(2) for the positive charged polymers P(AEA) and P(DMAEA). The directed coassembly of two different polymers (one charged and one noncharged) on the gold nanoparticle surfaces provided a mechanism (dependent on molecular weight) for shielding the surface charge imparted by the charged polymer component, allowing for a range of surface charges on the GNPs from -30 to +39 mV. In further work, the surface-charges were modulated by an external stimulus (temperature). The charge-modulation was controlled by the use of thermosensitive neutral polymers coassembled with charged polymers. The thermosensitive polymers exemplified in this paper are P(oligoethylene oxide acrylate-co-diethylene oxide acrylate) (P(OEG-A-co-DEG-A)) and P(N-isopropyl acrylamide) (P(NIPAAm). The temperature of the aqueous phase (from 15 to 70 degrees C) was then adjusted to tune the zeta potentials of the hybrid GNPs from +39 or -30 to approximately 0 mV. Finally, by manipulating the solution pH, reversible aggregation behavior of the hybrid GNPs could be induced.

Abstract
A well-defined N-(2-hydroxypropyl)methacrylamide-s-N-(3-aminopropyl)methacrylamide (HPMA-s-APMA) copolymer, synthesized via reversible addition-fragmentation chain transfer (RAFT) polymerization, was utilized for the rational design of multiconjugates containing both a gene therapeutic, small interfering RNA (siRNA), and a cancer cell targeting moiety, folate. The copolymer contains a biocompatible poly(HPMA) portion (91 mol %) and a primary amine, APMA, portion (9 mol %). A fraction (20 mol %) of the APMA repeats were converted to activated thiols utilizing the amine- and sulfhydryl-reactive molecule N-succinimidyl 3-(2-pyridyldithio)-propionate (SPDP). 5'-Thiolated sense strand RNAs were then coupled to the polymer through a disulfide exchange with pendant pyridyldithio moieties, giving an 89 +/- 4% degree of conjugation. The unmodified APMA units (80 mol %) were subsequently coupled to amine reactive folates with 81 +/- 1% efficiency. This yielded a multiconjugate copolymer with 91 mol % HPMA, 2 mol % RNA, and 6 mol % folate. siRNA formation was achieved by annealing antisense strands to the conjugated RNA sense strands. Subsequent siRNA cleavage under intracellular conditions demonstrated the potential utility of this carrier in gene delivery. The multiconjugate copolymer and siRNA release were characterized by UV-vis spectroscopy and polyacrylamide gel electrophoresis.

Abstract
Capillary electrophoretic separation of a mixture of 5'-fluorescein isothiocyanate-labeled single-stranded DNA (normal ssDNA) and its single-base-substituted one (mutant ssDNA) was achieved by using a RAFT-generated polyacrylamide-oligodeoxyribonucleotide block copolymer (PAAm-b-ODN) as an affinity polymeric probe. PAAm-b-ODN was synthesized through the Michael addition of thiol-terminated PAAm (PAAm-SH) to 5'-maleimide-modified ODN. PAAm-SH was derived from dithiobenzoate-terminated PAAm prepared via RAFT polymerization. The number-averaged molecular weight (M(n)) and the molecular weight distribution were determined by aqueous size exclusion chromatography. After a capillary tube was filled with the running buffer solution of PAAm-b-ODN, a mixture of normal and mutant ssDNA was subjected to electrophoresis and detected by a laser-induced fluorescent detector. Because the base sequence of PAAm-b-ODN was complementary to part of the mutant ssDNA, including a single-base substitution site, the electrophoretic migration of mutant ssDNA was retarded due to the formation of the equilibrium complex with PAAm-b-ODN. Increasing M(n) of the PAAm segment enhanced this retardation. On the other hand, normal ssDNA was unable to form the complex owing to a single-base mismatch, which was proved by melting curve measurements. The Lineweaver-Burk-type analysis of the mobility of mutant ssDNA revealed that the binding constants for the complexes with different PAAm-b-ODN probes were almost identical to each other. The analysis also demonstrated that the ratio of the hydrodynamic radius of the complex to that of the free mutant ssDNA increased with increasing M(n) of the affinity polymeric probe's PAAm segment. This means that the PAAm segment indirectly provides mutant ssDNA with an additional hydrodynamic friction force via the affinity interaction of the ODN segment. Optimization of the salt concentration of the running buffer and the capillary temperature improved the resolution of the separation. This affinity polymeric probe will be useful for developing a simple and highly reliable single-nucleotide polymorphism genotyping method.

Abstract
A Boc-protected aminooxy end-functionalized poly(N-isopropylacrylamide) (pNIPAAm) was synthesized by reversible addition-fragmentation chain transfer (RAFT) polymerization. The monomer was polymerized in the presence of a Boc-protected aminooxy trithiocarbonate chain transfer agent (CTA) utilizing 2,2'-azobis(2-isobutyronitrile) (AIBN) as the initiator in DMF at 70 °C. The final polymer had a number-average molecular weight (M(n)) of 4,200 Da as determined by (1)H NMR spectroscopy and a narrow polydispersity index (1.14) by gel permeation chromatography (GPC). The Boc group was removed, and the polymer was then incubated with N(ε)-levulinyl lysine-modified bovine serum albumin (BSA). Gel electrophoresis confirmed that the conjugation was successful. The aminooxy end-functionalized pNIPAAm was also immobilized on a gold surface after reduction of the trithiocarbonate end-group. The pNIPAAm surface was then incubated with an aldehyde-modified heparin to yield the polysaccharide-functionalized surface. All surface modifications were monitored by FT-IR spectroscopy.

Abstract
A new strategy is described for functionalizing the omega-terminal end of polymers synthesized by reversible addition-fragmentation chain transfer (RAFT) polymerization that provides spatially controlled bioconjugation sites. Traditional methods for preparing omega-functional polymers require the reduction of the RAFT chain-transfer agent to yield secondary or tertiary thiols of low reactivity or the synthesis of novel chain-transfer agents that contain reactive groups. As an additional strategy, N-substituted maleimido monomers have been used in a modified block polymerization to add a single maleimido unit onto the RAFT polymer with nearly quantitative efficiency. Unique reactive groups contained in the N-substituent are thereby added to the omega-terminal end of the polymer and are subsequently available for conjugation reactions. This technique has been demonstrated using N-(2-aminoethyl)maleimide trifluoroacetate to introduce a single primary amine to the omega-terminus of poly(dimethylaminoethyl methacrylate) and poly(N-isopropyl acrylamide) and to a specialized block copolymer for siRNA delivery. Evidence for retention of functional RAFT endgroups is provided by synthesis results where chain-extended polyDMAEMA (M(n) = 10 600 g/mol, M(w)/M(n) = 1.14) was used as a macro chain transfer agent for the polymerization of styrene, yielding a diblock polymer of low polydispersity (M(n) = 20 300 g/mol, M(w)/M(n) = 1.11). It is thus also possible to construct diblock copolymers with a bioconjugation site precisely located at the junction between the two blocks. The chain-extended polymers are functionalized with an amine-reactive fluorescent dye or folic acid at conjugation efficiencies of 86 and 94%, respectively. The versatile chain-extension technique described here offers unique opportunities for the synthesis of well-defined polymeric conjugates to molecules of biological and targeting interest.
